This happens with every popular new tech that does things differently from how its been done before. Since I've been developing I've seen it happen with
PHP
Rails
mongodb
now node.js
As long as there is a critical mass of developers that want to use a certain technology, there is nothing that anyone can do to stop it. They'll keep making it better and better until the naysayers have little or nothing they can criticize, and then it won't matter because everyone will be using it anyway.
Its great to see people stepping out to tamp down the hype though, that's the necessary next step in the evolution of any new tech.
